[PSUBS-MAILIST] Heating elements

Thu Aug 6 01:14:29 EDT 2015

Christopher,just looked at the reviews of that model, & it says...The operating instructions claim that the working environment for the unit is in temperatures between 68 and 104 degrees Fahrenheit and with a relative humidity level of fifty percent or higher. This means that in colder settings or lower humidity levels the crystals are inert, and also, this unit is not going to decrease the relative humidity below 50%. Factor that into your needs.
Saw some interesting peltier dehumidifyers for boats that were about20 watts & cost $50- on the site you linked to. RS components were selling  20W peltiers (just the peltier)for 63 British pounds. Alan

I have a friend that uses one of these crystal moisture absorbents in his gun safe and likes it. He plugs into the wall, heats the absorbed moisture out, unplugs it and returns it to the safe. It even has a type litmus gauge telling how how much moisture has been absorbed. 
This in not the one he has, just a reference.

Hey guys,

I´m looking for heating elements to mount in our electronic boxes and remote. Any pointers what to search for and where? I´m not even sure how they look like.

We have so far almost 250 dives with Malen this year, after the worst summer in decades with tons of rain in Sweden we´ll try to fight the moisture with some heating elements and a dehumidifier in the sub. The electronics does´t like to moisture for sure. All suggestions are super welcome.

Cheers, Lasse
